The solutions are effective only if they result in the closing of plants that are already producing greenhouse gases and atmospheric pollution. The example that I gave earlier was purely hypothetical. If we link Churchill Falls or any new hydroelectric dam and that results in the closing of six or seven coal-fired power stations in Ontario, there will indeed be a reduction. But if Churchill Falls or any other hydroelectric power station is linked to Ontario and no plants are closed and we merely add, we'll reduce carbon intensity, but we won't eliminate emissions.
